There were words that the RBR team were paying less attention on webbo's car. and putting more attention and priority on vettel's car.
Then there was a website counted each problem that both RBR drivers encountered since 2009.

They've found out Vettel shared similar amount of alternator problems and car issues as webber. Noticeably Korea 2010 and Silverstone 2013, Valenia 2012, spark plug issue in Bahrain 2010, Brake problem in Australia 2010. Other than these, most of Vette's problem occurred during practice and qualifying.
